Question
An inorganic compound (A) made of two most occuring elements into the earth crust, having a polymeric tetra-headral network structure. With carbon, compound (A) produces a poisonous gas (B) which is the most stable diatomic molecule. Compounds (A) and (B) will be
Options
A.SiO2, CO2
B.SiO2, CO
C.SiC,CO
D.SiO2’ N2
Solution
Sol. SiO2 + 2C → Si + 2CO
Compound A is silica (SiO2) made of Si and O2, two most occuring elements into the earth crust, having a polymeric tetraheadral network structure. Compound B is CO, a poisonous gas which is the most stable diatomic molecule
